Lecoq De Boisbaudran
Lecoq de Boisbaudran came of a well-to-do family of distillers, and received a good education from his well-educated mother. He set up his own chemical laboratory and in 1859 began to experiment in the new field of spectroscopy developed by Kirchhoff. After fifteen years of experimentation he discovered a new element in a sample of zinc ore and he named it gallium after France.|
In 1875, he presented the new element to the Academy of Sciences. Mendeleev read the reports and declared it to be a missing element he had named "eka-aluminium". Mendeleev proved to be right.
Lecoq de Boisbaudran went on to discover two more elements, samarium, in 1879, and dysprosium in 1886.
